A pH-responsive hydrogel consists of polypeptides only is a promising biomaterial with the advantages of good biocompatibility and non-toxicity. This work reports the synthesis of poly-L-ornithine(poc) (polyLOpoc) serving as the precursor for hydrogels of poly-L-ornithine (polyOrn) and poly(L-arginine-r-L-ornithine) (poly(Arg-r-Orn)). Their controllable degree of crosslinking, good mech. properties, good biocompatibility, and pH-responsibility are detailedly investigated. The swelling ratio of polyOrn hydrogel in acidic aqueous solution is 5.7 times higher than that in a basic environment. In the deprotection of phenoxycarbonyl group, polyLOpoc releases amino pendant groups, which attack the remaining poc-protected amino groups to fulfill self-crosslinking without any crosslinking agent. In addition, the pH-responsive behavior of hydrogels is visualized by aggregation-induced emission phenomena with polyOrn and poly(Arg-r-Orn) containing tetrakis(4-aminophenyl)ethene moisture. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Related Products of 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 102-09-0
